        ensures
            - This function takes the elements of a and splits them into two groups.  The
              first group remains in a and the second group is put into b.  The ordering of
              elements in a is preserved.  In particular, concatenating #a with #b will
              reproduce the original contents of a.
            - The elements in a are moved around using global swap().  So they must be
              swappable, but do not need to be copyable.
